본 연구에서는 반무한체에 대하여 활성화 에너지가 매우 큰 경우의 점근법을 적용하여 이 두 변수의 시간에 따른 변화가 점화지연시간에 미치는 영향을 해석적으로 알아보고 참고문헌(1)의 실험치와 비교하고자 한다.
The ignition of solid particle under strong convective heating has been investigated by applying an asymptotic analysis to a semi-infinite body for varying values of gas recovery temperature and convective heat transfer coefficient. It was found that if the scale of the reaction zone is much smaller than the characteristic length of the body size, then infinite body theory can be used to estimate the ignition delay time. Furthermore, the convective heat transfer coefficient was found to have more influence on predicting the ignition delay times of particle exposed to an incident shock wave rather than the gas recovery temperature.
